Description

Technical Field

[0001] The utility model relates to the technical field of industrial boiler connection welds, in particular to magnetic particle detection equipment for industrial boiler connection welds. Background Art

[0002] After the welding of the industrial boiler connection weld is completed, the welding quality of the weld needs to be inspected by a magnetic particle inspection mechanism. After searching, the patent with publication number CN112924539A discloses a permanent magnetic wheel type steel wall weld magnetic particle inspection automatic crawling device. When in use, the device includes a fixed large base plate and a walking mechanism, a magnetic particle inspection mechanism, a tracking mechanism and a stroke recording mechanism arranged on the fixed large base plate. The walking mechanism can walk close to the wall, but its walking direction is limited and it can only walk by grabbing the wall. In actual application, for example, at the industrial boiler connection weld, the furnace wall of the industrial boiler may be annular or have a convex arc. During the walking process, it needs to be taken down and then the furnace wall surface is changed to grab the wall and walk. This easily interrupts the detection of the magnetic particle inspection mechanism. Therefore, a magnetic particle inspection device for industrial boiler connection welds is designed that can continuously perform magnetic particle inspection on industrial boiler connection welds with different wall surfaces, improve the inspection efficiency while ensuring the continuity of the inspection. Utility Model Content

[0005] (2) Technical solution

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a magnetic particle inspection device for industrial boiler connection welds, comprising a polygonal frame, on which a polygonal ring walking mechanism and a detection frame that can rotate circumferentially around the center of the polygonal frame are provided. A magnetic particle inspection mechanism is fixedly installed on the side of the detection frame away from the center of the polygonal frame, and a magnetic plate is also fixedly installed on the bottom of the detection frame. The polygonal ring walking mechanism includes multiple groups of magnetic wall-grabbing wheels that are respectively rotatably connected to the corners of the polygonal frame, and also includes a walking drive component that synchronously drives the multiple groups of magnetic wall-grabbing wheels to rotate synchronously.

[0007] Preferably, weld distance meters are provided on both sides of the magnetic particle detection mechanism, and a controller is also included. The travel drive assembly and the two weld distance meters are electrically connected to the controller.

The center positions of the two regular polygonal side plates are fixedly connected with a transmission shaft sleeve, and the detection frame can perform circumferential rotation around the transmission shaft sleeve.

[0009] Preferably, the magnetic wall-grabbing wheel comprises two climbing rollers which are respectively arranged at both ends of the roller sleeve and fixedly sleeved with magnetic sleeves on the outside. The two climbing rollers are fixedly connected by a roller shaft which rotates and passes through the roller sleeve.

[0010] Preferably, the travel drive assembly includes a transmission shaft passing through a transmission sleeve, wherein a drive motor for driving one end of the transmission shaft to rotate is fixedly mounted on one of the regular polygonal side plates, and the other end of the transmission shaft is connected to a plurality of roller shafts through a transmission assembly, and also includes a plurality of guide assemblies adapted to the guide of the transmission assembly.

[0014] The magnetic particle inspection equipment for industrial boiler connection welds can be driven by a polygonal walking mechanism to rotate at the corners of the polygonal frame through a walking drive component, so that it can ride along the industrial boiler connection weld and grab the wall. If the industrial boiler connection weld passes through multiple industrial boiler wall surfaces, it can be replaced on another wall surface by rotating as a whole. At the same time, the inspection frame that can rotate around the center of the polygonal frame can manually move the magnetic plate toward the replaced wall surface after rotation. Under the magnetic attraction of the magnetic plate and the industrial boiler wall surface, the magnetic particle inspection mechanism is always directed toward the weld side and maintains a certain distance from the weld. The magnetic particle inspection equipment for industrial boiler connection welds can continuously perform magnetic particle inspections on industrial boiler connection welds with different wall surfaces, thereby improving inspection efficiency and ensuring inspection continuity.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example:

[0024] See also Figure 1-6 , a magnetic particle inspection equipment for industrial boiler connection welds, including a polygonal frame, a polygonal ring walking mechanism and a detection frame 10 that can rotate circumferentially around the center of the polygonal frame is provided on the polygonal frame, a magnetic particle inspection mechanism 11 is fixedly installed on the side of the detection frame 10 away from the center of the polygonal frame, and a magnetic plate 13 is also fixedly installed on the bottom of the detection frame 10, the polygonal ring walking mechanism includes multiple groups of magnetic wall-grabbing wheels that are respectively connected to the edges and corners of the polygonal frame, and also includes a group of walking drive components that synchronously drive multiple groups of magnetic wall-grabbing wheels to rotate synchronously. Further, the polygonal frame includes a triangular frame, a quadrilateral frame, a pentagonal frame, etc., and a triangular frame is preferably used to ensure overall stability while increasing the minimum angle between adjacent walls of an industrial boiler where the connection weld passes through multiple industrial boiler walls, further reducing the limitations of detection. Furthermore, the polygonal frame can be set to be a regular polygon or a non-regular polygon.

[0025] Specifically, weld distance meters 12 are provided on both sides of the magnetic particle detection mechanism 11, and a controller is also included. The travel drive assembly and the two weld distance meters 12 are electrically connected to the controller. By setting up two groups of weld distance meters 12, it is convenient to measure the distance of the industrial boiler connection welds, so that the two weld distance meters 12 are located on both sides of the industrial connection welds, so that the magnetic particle detection mechanism 11 is located between the connection welds, thereby improving the accuracy of magnetic particle detection. When the distances measured by the two weld distance meters 12 differ greatly, the controller will receive the signals from the two weld distance meters 12, edit them, and transmit them to the travel drive assembly, causing it to stop moving. After the position is adjusted, it can be driven again.

[0026] Specifically, the polygonal frame includes two relatively arranged regular polygonal side plates 1, and the relative multiple corners of the two regular polygonal side plates 1 are fixedly connected by roller sleeves 2. The center positions of the two regular polygonal side plates 1 are fixedly connected with a transmission shaft sleeve 6. The detection frame 10 can perform circumferential rotation around the transmission shaft sleeve 6. The transmission shaft sleeve 6 and multiple roller sleeves 2 facilitate the connection of the two regular polygonal side plates 1, and facilitate the circumferential rotation of the detection frame 10 around the transmission shaft sleeve 6.

[0027] Specifically, the magnetic wall-grabbing wheel includes two climbing rollers 3 which are respectively arranged at both ends of the roller sleeve 2 and are fixedly sleeved with magnetic sleeves 4 on the outside. The two climbing rollers 3 are fixedly connected by a roller shaft 5 which rotates through the roller sleeve 2. When walking, the two climbing rollers 3 are mounted on both sides of the connecting weld to walk through the two climbing rollers 3 with magnetic sleeves 4 on the outside. Through the setting of the magnetic sleeve 4, they can walk with the industrial boiler wall by magnetic suction.

[0028] Specifically, the walking drive assembly includes a transmission shaft 7 passing through a transmission sleeve 6, wherein a driving motor 8 for driving one end of the transmission shaft 7 to rotate is fixedly mounted on one regular polygonal side plate 1, and the other end of the transmission shaft 7 is connected to multiple rollers 5 through a transmission assembly 15, and also includes multiple guide assemblies 16 adapted to the guide of the transmission assembly 15. Furthermore, the transmission assembly 15 can be set to a sprocket chain or belt pulley transmission connection, and the guide assembly 16 can be set to a guide sprocket or guide pulley, preferably a sprocket chain or a guide sprocket.

[0029] Specifically, a rotating sleeve 9 that can rotate and slide with the transmission shaft sleeve 6 is fixedly installed on the detection frame 10. Limiting rings 14 fixedly connected to the transmission shaft sleeve 6 are provided on both sides of the rotating sleeve 9. Through the setting of the rotating sleeve 9, the detection frame 10 can conveniently drive the magnetic particle detection mechanism 11, the weld distance meter 12 and the magnetic suction plate 13 to rotate around the transmission shaft sleeve 6 as a whole. Through the setting of the limiting ring 14, the rotating sleeve 9 can be conveniently limited to prevent the rotating sleeve 9 from moving left and right.
